Remove Reha Ransomware Virus

Reha is one of the DJVU ransomware variant discovered by Michael Gillespie aka Demonslay335. Just like a typical ransomware, it prevents access to files by encrypting it using complex algorithm. The only way the user to open the file is paying a ransom fee to developers. Reha ransomware renames the encrypted files by adding extension .reha. Therefore photo.jpg will become photo.jpg.reha. A text file named _readme.txt also appears with a message from Reha developers notifying the victims on how to decrypt important files.

What is the Reha text file consisting of?

Typically, the text file contains the instructions or demand of Reha authors. A ransom fee is ranging from $490 to $980 and this cost varies depending on terms and conditions of Reha developers. Nevertheless, sometimes forcing the victims to purchase a tool or key to decrypt the files is the way of cyber criminals to generate money from this kind of scheme. Appropriate decryption tools or key is necessary to recover the encrypted files. Unfortunately, developers of Reha can only provide this to the victims as of this moment. People behind the ransomware virus demanded that victims must contact them through email address presented on the ransom note within 72 hours.

How Reha ransomware infect computers?

As usual, Reha ransomware can get through computers by means of spam email campaigns, untrustworthy download sites, fake software updates, or even activating tools. Through email campaigns, Reha developers attached malicious files and once it is opened or clicked it will automatically install malicious software. The best example of files that can infect computer includes:

  • PDF documents
  • JavaScript files
  • Executable files (.exe.)
  • Archive files (RAR and ZIP)
  • Microsoft documents (.doc, .xls, .ppt)

Reha ransomware is also possibly comes from clicked ads from untrustworthy download sites that supports false updates or search results.

Infection Signs and Recovery of Reha Encrypted Files

User’s files or documents are inaccessible once it is encrypted by Reha ransomware virus. Previously functional files are renamed and locked. A demand message from Reha developers is generated for the perusal of its victims. A ransom fee must be paid generally in exchange of recovering the entire Reha decrypted files.

To restore from a backup file is the only alternative way to recover corrupted files without having to pay the ransom fee or purchasing a tool from Reha developers. Note that all important documents should properly store in a safe media because we can never know how and when these cyber criminals would attack.
